The airplane disappeared from radar coverage and was located in a wheat field by Sheriff Department personnel. The airplane sustained an in-flight airframe breakup. Airframe components recovered from the accident site were submitted to the NTSB Material Laboratory for examination. The examination revealed all failures were due to overload. Examination of the airframe revealed the airframe design limits were exceeded. The pilot received several preflight briefings through the use of the DUAT system. The products used forecasted thunderstorm activity along the route of flight and the pilot received Convective SIGMET's and Central Weather Advisories warning of developing thunderstorms.
